Did not sign out an ipad before changing my apple ID now I can't sign in on the old ipad, but the new iphone and new ipad are working great with new Apple ID.
I did not sign out of my old Ipad before changing my email to my new email when I retired (as my apple ID). Now I can't sign into the old iPad, but the new iPad and iPhone work great.
How do I fix this? I added my old email as a secondary email, but it still doesn't let me sign out of the old iPad.
iPad, iPadOS 14
